Explanation:

When using a grinder on a platform, safety is crucial. Pressing metal to the disc before starting the grinder is dangerous as it can cause the grinder to jerk. Pressing forcefully against the metal while grinding can lead to loss of control. Wearing rubber footwear is a general safety measure but not specifically important for this context. Using a flame - retardant blanket to catch falling sparks is important as sparks from grinding can be a fire hazard.

Answer:

use a flame retardant blanket to catch falling sparks
